Function Documentation

void HAL_NVIC_DisableIRQ ( IRQn_Type  IRQn )

Disable a device specific interrupt in the NVIC interrupt controller.

Parameters:
IRQnExternal interrupt number. This parameter can be an enumerator of IRQn_Type enumeration (For the complete STM32 Devices IRQ Channels list, please refer to the appropriate CMSIS device file (stm32l4xxxx.h))
Return values:
None

Definition at line 239 of file stm32l4xx_hal_cortex.c.

void HAL_NVIC_EnableIRQ ( IRQn_Type  IRQn )

Enable a device specific interrupt in the NVIC interrupt controller.

Note:
To configure interrupts priority correctly, the NVIC_PriorityGroupConfig() function should be called before.
Parameters:
IRQnExternal interrupt number. This parameter can be an enumerator of IRQn_Type enumeration (For the complete STM32 Devices IRQ Channels list, please refer to the appropriate CMSIS device file (stm32l4xxxx.h))
Return values:
None

Definition at line 223 of file stm32l4xx_hal_cortex.c.

void HAL_NVIC_SetPriority ( IRQn_Type  IRQn,
uint32_t  PreemptPriority,
uint32_t  SubPriority 
)

Set the priority of an interrupt.

Parameters:
IRQn,:External interrupt number. This parameter can be an enumerator of IRQn_Type enumeration (For the complete STM32 Devices IRQ Channels list, please refer to the appropriate CMSIS device file (stm32l4xxxx.h))
PreemptPriority,:The pre-emption priority for the IRQn channel. This parameter can be a value between 0 and 15 A lower priority value indicates a higher priority
SubPriority,:the subpriority level for the IRQ channel. This parameter can be a value between 0 and 15 A lower priority value indicates a higher priority.
Return values:
None

Definition at line 201 of file stm32l4xx_hal_cortex.c.

void HAL_NVIC_SetPriorityGrouping ( uint32_t  PriorityGroup )

Set the priority grouping field (pre-emption priority and subpriority) using the required unlock sequence.

Parameters:
PriorityGroup,:The priority grouping bits length. This parameter can be one of the following values:

  • NVIC_PRIORITYGROUP_0: 0 bit for pre-emption priority, 4 bits for subpriority
  • NVIC_PRIORITYGROUP_1: 1 bit for pre-emption priority, 3 bits for subpriority
  • NVIC_PRIORITYGROUP_2: 2 bits for pre-emption priority, 2 bits for subpriority
  • NVIC_PRIORITYGROUP_3: 3 bits for pre-emption priority, 1 bit for subpriority
  • NVIC_PRIORITYGROUP_4: 4 bits for pre-emption priority, 0 bit for subpriority
Note:
When the NVIC_PriorityGroup_0 is selected, IRQ pre-emption is no more possible. The pending IRQ priority will be managed only by the subpriority.
Return values:
None

Definition at line 179 of file stm32l4xx_hal_cortex.c.

void HAL_NVIC_SystemReset ( void   )

Initiate a system reset request to reset the MCU.

Return values:
None

Definition at line 252 of file stm32l4xx_hal_cortex.c.

uint32_t HAL_SYSTICK_Config ( uint32_t  TicksNumb )

Initialize the System Timer with interrupt enabled and start the System Tick Timer (SysTick): Counter is in free running mode to generate periodic interrupts.

Parameters:
TicksNumb,:Specifies the ticks Number of ticks between two interrupts.
Return values:
status,:- 0 Function succeeded.

  • 1 Function failed.
